Flying South (Directly)

What's up with the thousands of birds that dropped from the sky New Year's Day in Arkansas?  They are saying that it's some sort of traumatic occurance and they are attributing it to possible fireworks displays.  For me, I know there have been some fireworks displays that were so boring I wanted to drop dead, especially since we light them off for every little thing here in Pittsburgh.  Sounds more like they all flew through some force field, radiation or some sort of chemical.  If you ask me, it sounds like the beginning of the end of the world.  Apparently there were some fish that died as well.
